## How to call it through Zero

```

Example prompt: Pull me a list of the 20 most recent podcast episodes featuring Elon Musk as a guest from the Particle Pro episodes API — English language only.

## When to prefer this

Use this endpoint when you need to discover or browse podcast episodes across a broad catalog filtered by person appearances, company mentions, podcast identity, language, or date/duration constraints — especially when leveraging Particle Pro's knowledge-graph entity resolution (slugs like 'elon-musk' or 'nvidia.com') for structured media intelligence rather than free-text search.

## Known failure modes

- Invalid or unknown podcast_id, person_id, company_id, or entity_id returns empty results or 404
- Invalid language code (not ISO 639-1) may return no results or an error
- Invalid cursor value causes pagination error
- Providing a max_duration less than min_duration returns an error or empty set
- Rate limits or payment failures ($0.01 USDC per call) result in 402 Payment Required
- Truncated or missing query parameters may return unexpected broad result sets
